130 PICO Question Summary
|
131 Introduction |
|
132 Active compression-decompression (ACD) CPR uses a handheld device with a suction cup applied to the midsternal region in human patients to allow active lifting of the chest wall during the chest decompression phase of CPR. This enhances negative intrathoracic pressure generated during chest recoil, augmenting venous return. This PICO question investigated the utility of ACD CPR in dogs and cats.
|
|
133 Consensus on science |
|
134 Outcome 1: Favorable Neurologic Outcome:
135 For the critical outcome of FNO, we identified 7 clinical trials (very low quality of evidence, downgraded for serious risk of bias and very serious indirectness) and 1 observational study (very low quality of evidence, downgraded for serious risk of bias and very serious indirectness) that addressed the PICO question.1–8 All studies were in people. One clinical trial showed improved FNO with ACD, but this was not repeatable in the other trials.1,3–8 The observational study failed to demonstrate a difference.2
136 Outcome 2: Survival to Discharge:
137 For the next critical outcome of survival to discharge, we identified 12 clinical trials (very low quality of evidence, downgraded for serious risk of bias and very serious indirectness) and 1 observational study (very low quality of evidence, downgraded for serious risk of bias, and serious indirectness) that addressed the PICO question.2,4,5,7–13 All studies were in people. Of the relevant human clinical trials using ACD-CPR compared to standard CPR, none found a significant difference in survival to discharge.4,5(p9),7,8(p5),9–14 The observational study failed to demonstrate a difference.2
138 Outcome 3: ROSC:
139 For the important outcome of ROSC, we identified 11 clinical trials (very low quality of evidence, downgraded for serious risk of bias and very serious indirectness), 3 experimental studies (very low quality of evidence, downgraded for serious risk of bias and serious indirectness), and 1 observational study (very low quality of evidence, downgraded for serious risk of bias and serious indirectness).4,5,7–17 Of the relevant human clinical trials evaluating the use of ACD-CPR compared to standard CPR, these studies yielded mixed results, but overall do not support that ACD-CPR improves ROSC.1,3,5–9,11–13,18 There are no relevant veterinary studies.
140 Outcome 4: Surrogate markers of Perfusion:
141 For the important outcome of surrogate markers of perfusion, we identified 15 experimental studies (very low quality of evidence, downgraded for serious risk of bias and serious indirectness).15–17,19–30 An experimental dog study provides evidence that ACD increases LV pressure/time, coronary perfusion, cardiac output, and pulmonary artery flow.23 Increased minute ventilation with ACD has also been shown.20 A study of 8 beagle dogs showed increased cerebral and pulmonary blood flow in dogs during ACD-CPR compared to conventional CPR.22 Several porcine experimental models show improvements in surrogate markers (cerebral, carotid, renal or myocardial blood flow, cardiac output, or blood pressure) with ACD-CPR.15–17,19,21,24–30 |
|
142 Treatment recommendation |
|
143 We recommend against the use of active compression-decompression CPR in dogs and cats (strong recommendation, expert opinion).
|
|
144 Justification of treatment recommendation |
|
145 The majority of the evidence evaluated did not support a benefit of ACD during CPR in human patients, despite the fairly consistent improvement in surrogate markers of perfusion found in experimental animal studies. In addition, adherence of the ACD device’s suction cup to the thoracic wall, and thus the applicability to dogs and cats in the clinical setting (i.e., those with full haircoats) is limited.
|
|
146 Knowledge gaps |
|
147 Evaluation of prioritized outcomes (favorable neurological outcome, survival to discharge) for ACD-CPR versus conventional CPR in dogs and cats is needed to help determine whether clipping fur during CPR to apply an ACD would be worthwhile. Alternatively, development and evaluation of safe, clinically applicable ACD equipment in dogs and cats would be needed.
